Make the best of your videos and pictures with the FitLine Phone Grip. The phone grip can function as a convenient stand so you can comfortably and easily watch videos. Additionally, you can remove the top to charge your phone wirelessly.
Dimensions: 38.8 mm diameter x 7.7 mm H (24.3 mmH expanded)
Works with: any smooth, hard plastic case.
Doesn't work with: silicone, highly textured surfaces, and many soft cases. Does not stick "as well" on iPhones themselves.
While it does stick adequately to a base model without a phone case (and sometimes to Pro/Promax depending on circumstances), it will not stick as well as it does on a suitable case.
